I would like to set up a small mastering rack just before sound output
for live shows, this is on linux. Essentially I'm hoping to have about
8-12 channels of audio go out of csound5 via jack and into some sort of
host for plugins and mixing down to four channels of final audio out.
All I want to run are a few compressors and some eq, with easy access to
the control parameters and graphic vu meters of the compression. Ideally
these plug ins would also be controllable via midi cc's and some form of
API so I can make my own gig front end integrated with my csound user
interface. Questions:
Is this feasable with csound5 now? Has anyone gotten multi-output
working well with Jack?
What should host the plugins? Ecasound looks promising, but will I be
able to get graphic vu meters of the compression action? Does that even
work properly, ie can the screen respond fast enough? Anything else I
should look into? Jammin seems heavy me thinks.
Which plugins should I use? I'd like minimal cpu use, but a good easy
over compressor ( soft-knee ), a good final limiter, graphic eq, and
paramateric eq. Compressor must have accurate controls for attack,
release, ratio, threshold, and some form of knee control.
Is this even feasable? Are the LADSPA plug-ins good enough now to
replace hardware in the $300 compressor, $100-200 eq range? I don't
expect it to sound as good as TL-Audio tubes or anything, but I won't
drop $300 on an FMR or buy a bunch of ProSonus's if a plugin can sound
as good as that.
All suggestions welcome, thanks.

Have you looked at JAMin? http://jamin.sourceforge.net

I feel JAmin will require with multiple tracks a lot of hardware resources
while running and I think it only takes one stereo input(can not check it
up because im re-installing my mach :) But I have used JAmin with ardour
with multiple tracks/final mixdown and it works pretty well . To play
these things live will require a nice sound card, which can give you
low-latency audio that is very crucial with live audio. LADSPA Pugins are
very good and some audio people will totally disagree that software can
replace good hardware for live sound, but you can always trust your ears.

Sounds like JAMin to me. (Yes it's heavy, but good).

I can only do a stereo input to Jammin, correct? I was thinking of
running 3-4 stereo groups into the final stage and doing subgroup
mastering and mixing, but I guess I could either do two stages, ie
ecasound with 3 pairs into jammin. It occured to me that I may solve the
cpu problem by just using a second machine with 8 outs from the first
into the second thus allowing the second ( a 1400 Athlon ) to be used
for just ecasound/jammin.
Now, is it possible to automate jammin from external controls? It didn't
really look like that to me at first glance, but if the quality is way
better than using externally controllable plugins with ecasound, then
maybe that's more important.
Thanks for the feedback

You can do scene changes using OSC. There are 20 available scenes.
I'm not sure how you do it. Ron Parker has been working on it. Steve
probably knows how as well. Ron's using Ardour to control the scene
changes.

Hi Iain,
I am starting to use csound with jack, and it supports multichannel full
duplex with the only limitation that if you use input, -b must be a
multiple of ksmps. I'm using:
csound -b512 -B128 --sched -+rtaudio=jack -iadc:alsa_pcm:caprute_
-odac:alsa_pcm:playback_ -M0 -m0
And it is receiving midi and producing audio without glitches. Needs
some more reliability testing, but it's working.
As for a compressor with visual feedback, the only one I've seen is
jamin, but it might be overkill for your purposes and if you plan to add
jamin to all your tracks you need to run four+ instances (since jamin is
stereo) and that would drown most cpus. Plus there's a problem when
compressing several tracks with independent compression: image shift.
When compressing multichannel signals, the compressors should be linked
so that any reduction in any channel is reflected in the rest of the
channels, otherwise you get image shifting. I don't think there is an
octo-compressor for linux, and there probably isn't one for windows
either (maybe 6 channel). (maybe it can be designed with csound?)
I can't comment on the quality of the compressors, but I guess they are
Ok, and for a live setting more than enough. I would like to hear
opinions on this.
Cheers,
Andres
